HPR SERIES

Models HPR5-10 through HPR50Warm saturated air enters the Evaporator where it is cooled by refrigerant being controlled by a Constant Pressure Expansion Valve. Water vapor condenses into a liquid for removal at the moisture separator by an Automatic Drain. The cold, dry air is reheated as it passes through the Re-heater. This prevents pipeline sweating. The Static Condenser eliminates the need for a cooling fan and simplifies the system.

Models HPR75 through HPR500 Warm saturated air enters the air-to-air heat exchanger where it is pre-cooled by the outgoing chilled air, and then passes through the air-to-refrigerant (evaporator) heat exchanger where it is further cooled by the refrigeration system. Water vapor condenses into liquid droplets to be removed by the Moisture Separator then, discharged from the dryer by an automatic drain. Chilled dry air returns through the air-to-air heat exchanger where it is reheated before exiting the dryer.
